To all whom it may concern: I

Be it known that I, Amen N. MUMMERT,

a citizen of the United States, and a resident of Goshen, in the county of Elkhart and State of Indiana, have invented a new and Improved Dust-Collecting Bag for Vacuum-Cleaners, of which the following is a full, clear, and exact description. This-invention relates to new and improved dust collecting bags for vacuum cleaners, and more particularly to an improved bag for this purpose which is constructed of a single blank section of paper of cloth capable of convenient attachment to and removal from a vacuum cleaning machine, the device being so inexpensively constructed that. after it has been filled with dust and sweepings it may be destroyed or burned with the latter, thus obviating the necessity of coming in contact with or inhaling the dust and dirt.

In connection with electric or other vacuum cleaners as now generally constructed, it is common to use a cloth bag which catches the dirt from the discharge of the blower casing, and these bags are so expensively constructed that they must be removed and emptied when full, to permit continued operation .of the cleaner, resulting in considerable inconvenience both in the disagreeable manner in which the bag must be removed or attached, as well as causing considerable annoyance by coming in contact with the dust and disease laden germs on account of it being necessary to empty the receptacles.

The present invention is designed to overcome these defects and objections, and further embraces a novel bag or pouch construction having an inlet portion or tube formed integrally with the blank and di rected or disposed within the area of the bag for discharging the dust therein and preventing the escape of the latter until the bag has become full, while novel and inexpensive means are also provided for removably securing the bag to the discharge member of the cleaner and to the handle thereof, whereby the bag may be conveniently removed and a new one substituted. With the above and other objects in view, the inventlon resides more particularly in the peculiar combination and arrangement of parts which will be illustrated as a preferred embodiment in the accompanying drawings and described in the specification.

Reference is to be had to the accompanymg drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views and in which Figure 1 is a side elevation of my improved dust collecting bag attached to a well known form of pneumatic carpet sweeper; Flg. 2 is a vertical sectional view of the bag slightly enlarged with respect to that shown in Fig. 1; Fig. 3 is a plan view of the blank from which the bag is constructed; and Fig. 4 is a horizontal sectional view of the improved bag taken on the line 4.-4 of Fig. 2.

In the illustrated embodiment of the inventlon, the numeral 10 indicates the motor casing of an ordinary vacuum cleaner having the mouth or suction piece 11 and an' outlet or discharge member 12, there also being a handle 13 which is pivoted or otherwise attached to the motor casing containmg the usual blower or suction fan, whereby the machine may be advanced acrossthe floor or otherwise conveniently handled. This structure is used to show the practical use and application of the invention, of which' it forms no particular part, as the device may be applied to various machines of the vacuum type to which bags can be attached for catching the dirt and sweepings.

The bag proper is indicated by the numeral 14;, the same consisting of a single blank section of material, either paper or cloth, of such texture that dust and sweepings will readily adhere to it, as for instance, canton flannel or crepe paper, the latter of which is illustrated in Fig. 4 of the drawings. The blank from which the bag or pouch is constructed is substantially fish shape or egg shape, except that the top portion thereof is severed to provide oppositely sloping edges 15, while the bottom' portion thereof is provided with a fish tail extension 16 of reduced width relative to the width of the blank, whereby when the blank isfolded vertically it 'will take the form of a semi-egg shaped bag or pouch, as shown in Flgs. 1 and 2 of the drawings. The blank to one side of its horizontal center, referring to the position shown in Fig. 3 of the drawings, is slightly wider than the opposite side, so that when the blank is folded as described the extended part indieated by the numeral 17 is re-bent or folded over the edge 18 at the opposite side of the blank and stitched thereto, as shown at 19, so that the bag is considerably strengthened for all desirable purposes,. whether constructed of cloth or paper.

The upper edge of the blank is folded, as shown at 20, and stitched as shown at 21 to provide a hem for reinforcing the open upper end of the bag or pouch, whereby it may be suitably held by a clamp 22 and supported from the handle as by means of a flexible connection 23. The extension 16 has its vertical edges stitched together, as shown at 24:, and the inlet portion or tube thus provided is turned into the bag proper in the manner shown in Fig. 2 of the drawings, it being observed that the tapered formation of the extension causes it to be enlarged upwardly toward its free end to permit the unobstructed escape of the dust, dirt and sweepings into the bag.

To attach the bag to the discharge member 12, a section of cord or tape 25 is stitched to the bag, preferably by means of the stitching 19, and after the reduced portion or extension of the bag is slipped over the discharge member in the manner shown in Fig. 1 of the drawings, such fastening means is tied there-around, thus permitting convenient attachment and removal of the bag. It will also be observed that considerable s ace is provided around the tube 24 in which the dust and dirt are received, so that it is obvious that when the bags are made of con siderable size they may be used for a considerable length of time, and may be destroyed or burned to obviate the inconvenience of coming in contact with or inhaling the dust and sweepings. By this means extremely sanitary conditions are provided for and the value of vacuumcleaners for universal use greatly enhanced.

The bag may be used separately in the manner described, or secured in any of the outer bags or compartments commonly used with dust collectors or vacuum sweepers, and removed to be destroyed or burned with the sweepings and another bag inserted. Also, by reason of the peculiar construction or shape of the bag, increased area is provided within the ba at the bottom and around the inlet tube or the collecting and holding of a large amount of dust and sweepings without permitting the return thereof to the cleaner.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A dust collecting bag for vacuum clean- I ers, comprising a body having astraight forward edge, a curved rearward edge and a reduced integral bottom extension forming a tube said tube being turned into the bag to be adjacent the straight forward edge to form a surrounding storage space.

2. A destructible dust collecting bag for a bag being constructed of such material asto cause dust and sweepings to adhere to the interior surface thereof, said bag comprising a single fish-shaped blank folded upon itself and having its free end portions secured to gether to provide upper and lower openings.

3. A dust collecting bag for vacuum cleaners, comprising a body having a reduced integral bottom extension forming a tube, said tube being turned into the body to form a pouch surrounding the tube whereby return of the heavy particles to the cleaner is prevented.

4. A bag of the class described, comprising a blank section of material having its top portion severed and its lower portion provided with a fish tail extension, said blank being folded upon itself and having its free edges stitched together to produce open ends, the extension producing a tapering tube, said tube being folded into the area of the bag;

5. A bag of the class described, comprising a blank section of material having its top portion severed and its lower portion provided with a fish tail extension, said blank being folded upon itself and having its free edges stitched together with the ends open, the extension said tube being folded into the area of the bag, and means attached to the bag adjacent said tube for securing the same to the discharge member of a vacuum cleaner.

6. A bag of the class described, comprising a blank section of material having its top portion severed and its lower portion proproducing a tapering tube,
